Tirupur Dye Houses closed

Tirupur in India is one of the world’s centres for clothing production. Sitting next to the city of Coimbatore, Tirupur is a place I have visited on a number of occasions, to visit factories, print shops, dye houses and so on.

Principally Tirupur is home to knit wear factories, they make tee-shirts and other knitted cotton items, many of which find their way to high street chains here in the UK.You may be wearing something right now that was made in Tirupur.

Certainly if you buy from shops like supermarkets or the larger chain stores, then there is a very good chance you have items which were made in Tirupur. But as well as being home to a few high standard production units, Tirupur has also struggled in recent years, with a reputation for production facilities which are not what they could be – or should be. Where workers are, if not necessarily mistreated (although sometimes that is the case), then not given the respect or conditions that they deserve. This is not a malice thing, it is about costs. If you are looking at saving a few cents on each garment, then you arent going to spend as much on your workforce, or their workplace.

Hand in hand with this kind of treatment of humans, has gone harsh treatment of the environment. One of the most environmentally damaging aspects of the clothing supply chain is the dye process – because of the scale of production, the dye plants are huge things, with massive amounts of chemicals used on a daily basis. The usual process for the kind of fabric which teeshirts are made of, is Jet dyeing, where fabric is zoomed through a process where jets of hot water containing dye and other chemicals are pumped into them – this process uses large amounts of electricity, steam and of course the chemicals themselves.

The problem comes of course, not so much in the dyeing process itself, which is energy intensive but contained,  but in the disposal of effluent.  There has to be an issue of effluent after the dying process, and it will necessarily contain, among other nasties, large quantities of salt – as anyone who has dyed a piece of fabric at home will know.

The cheapest way of getting rid of such effluent is to dump it in a water course, and that is what most operators do, they simply pump their polluting effluent into nearby rivers. This kind of pollution has meant that the agricultural land in the area has been badly affected by pollution and salination over a number of years.

Attempts have been made to set this right, plants have been prosecuted and closed down, even the British government got involved (they realised we import 90%+ of our clothes, and recognised we have some responsibility to the producers) and for a while Tirupur began to be held up as an example of ‘best practise’. Levels were set to regulate the amount of salt in effluent, to try and protect the surrounding farmland, and it all seemed to be going in the right direction.

Not for long of course.

This week comes the news that Madras high court has ordered over 700 dye plants to be shut down – yes, 700. The local electricity board has begun to shut off power to those who have failed to comply with the order. The reason is that the level of salt in the effluent discharged into the local water courses is too high. Once again farmland has been terribly damaged by discharge of salt – and its the dye houses which are to blame.

As it stands the 700 plants are on shut down, thousands of jobs which go with that are at risk or already lost – suppliers will not be getting their materials, clothing supply will be affected. Farmland is polluted and will not produce a proper harvest this year, and meanwhile people continue to buy cheap clothes because they dont see the link.

I actually feel rather sorry for the dye house owners and operators, they are in a hard world, trying to provide a service against very tight price demands – I genuinely feel that we, the consumers and producers are not really being fair on them.

I feel that at the centre of it all, it’s our consumption that is driving this pollution problem, it’s our quest for a bargain that is putting lives and livelihoods at risk, and it’s our choices which have meant that today many poor people stand on the brink of ruin.

So yes, 700 dye houses are closed today, and I’m sorry to have to tell you that it is pretty much our fault.
